Title: Improvements in and relating to vapour burning apparatus
IPC: F23D11/44
Filed: 1932-03-10
Abstract: 388,219. Vapour burners. JUNKER & RUH AKT.-GES., Siemensstrasse, GUHL, H., 5, Richard Wagnerstrasse, DORL, F. W. O., 6, Liebigstrasse, and GARGEL, K., 42, Bannwaldallee, all in Karlsruhe, Baden, Germany. March 10, 1932, No. 7198. [Class 75 (i).] Vapour - burning apparatus is provided with at least two interconnected compartments containing fuel, one compartment housing the end portion of the fuel supply pipe which is provided with an inlet aperture not greater than the outlet aperture of the vaporizer nozzle, the arrangement being such that the air-fuel mixture necessary for preheating the vaporizer is derived from the said compartment and after the consumption of a predetermined amount of air, an automatic change-over to the normal operation of the burner is effected without the actuation of a tap or like member. As shown in Fig. 5, fuel containers 13, 15 are arranged side by side and are connected by a pipe 17, the latter container being fitted with an air pump 14 and housing the lower U-shaped end 1 of the fuel supply pipe 3, provided near the U-bend with the inlet aperture 6. If the upper end of the pipe 3 is closed, as by a tap 9, and air is pumped intd the container 15, the level of the fuel in the container will be depressed to the level a-a and air will pass through the connecting pipe 17 into the container 13. If now the tap 9 be opened, air from the container will pass through the fuel in the U-bend and the fuel-air mixture will pass up the pipe 3, through the vaporizer 4 to the burner 12 disposed beneath the vaporizer. As the air is consumed the level of fuel in the container 15 will rise till it covers the end of the pipe 1. The remaining air pressure in the other container 13 will then serve to supply liquid fuel to the vaporizer. In modified forms, the container 15 is arranged above or below the container 13. The fuel supply pipe is provided with valve means adapted to cut off the supply of liquid fuel and prevent flooding should the tap be open and the burner not ignited. As shown in Fig. 9 the said means comprises a chamber 65 containing a float 66 with apertures 67 for the fuel and a valve cone 68. Alternatively the valve may comprise a ball operating in a chamber of slightly greater diameter. The supply of liquid fuel to the vaporizer and of vapour to the burner are simultaneously controlled by means of a conical valve 86 having a shaft 84 extending through the vaporizer and forming a needle valve 85 at the outlet nozzle 93.

Abstract: 821,079. Refrigerating; heat pumps. HEAT PUMP & REFRIGERATION Ltd. Feb. 21, 1958 [March 5 1957], No. 7350/57. Class 29 In a compression heat pump system supplying heat to a water system the condenser comprises an inner tube 3 through which compressed refrigerant flows and an outer tube 5 through which water or other liquid to be heated flows in counter-current direction. The compressor 2 is located in an insulated chamber 1 containing oil or other coolant located preferably beneath a kitchen sink. On leaving the condenser refrigerant flows through a drier 7 and restriction valve 8 and then either through restriction valve 12 to evaporator 15 and line 10<SP>1</SP> to evaporator 9 or directly to evaporator 9 through solenoid valve 11. Evaporator 15 is located in a domestic refrigerant cabinet and the temperature in the cabinet controls the operation of solenoid valve 11. A fan 19 induces a flow of air over evaporator 9 and is controlled by a thermostat 22 at the inlet of water heating coil 5, being brought into operation by a low water temperature. A thermostat 23 at the outlet of the water coil controls a solenoid valve 24 through which excessively hot water runs to waste. The lines 10<SP>1</SP> and 20 are preferably flexible or semiflexible tubing and do not exceed the length of the evaporator coil 9. Hot gas defrosting may be provided by connecting a line containing a solenoid valve between the outlet of the compressor and a point on the far side of restrictor 8, operation being controlled by a thermostat at the outlet of evaporator 9. In an alternative construction the chamber 1 containing coolant is formed as a jacket about the compressor and the condenser and water coil soldered to the outside of the jacket. The coil 5 may itself only form a heat transfer system to a water tank and may then be filled with oil.

Title: Improvements in or relating to record card controlled statistical machines
Inventor: PERRIN JOHN
Filed: 1951-05-02
Abstract: 694,420. Statistical apparatus. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. May 2, 1951, No. 7545/53. Divided out of 694,365. Class 106 (i). In order to check that a card column contains only one punching by segregating any card which contains no perforation or two or more perforations, the apparatus comprises two card-receiving pockets disposed one in advance of the other, a deflector normally to direct cards into one of the pockets and a timing device cooperating with the deflector to cause it to direct a card into the other of the pockets, and is characterized by checking- means to sense individual columns of a perforated card, and electrical circuit means including a timing device actuator common to all the checking means and an actuator control element for each card column to be checked, each actuator control element causing operation of the common actuator on activation by the checking means, due to the checking means sensing that a card column contains either no perforation or two or more perforations. The cards are punched at 14, Fig. 2, in accordance with marks 13 made in the columns 12 by apparatus described in the parent Specification 694,365, in order that the cards may control known forms of punched record card controlled machines. The cards are fed to vertically reciprocable sensing chamber 19, Fig. 4, which in known manner has sensing-pins 20 and transmission rods 21 co-operating therewith. The upper end of each rod 21 supports a cylindrical contact element 22 comprising an integral conductor element 23 and a shorting ring 24 insulated from elements 22 and 23, the ring 24 and element 23 having their contact faces separated by contiguous insulator ring elements 25. The contact elements 22 pass through a conductor plate 26 and are urged towards the rods 21 by springs 29. Fixed contact elements 30 depend from a plate of insulating material. The contacts 30 are connected via terminals 32 with a solenoid 33, Fig. 5, through resistances 34. In the upper column, Fig. 5, a hole has been sensed at No. 5 position, this places the resistance 34 in series with the relay 35 so that the potential applied thereto is insufficient to operate it. In the centre column 21 holes have been sensed in the card and since no resistance 34 is in circuit the full potential is applied to solenoid 33 which is operated thereby. In the lower column two holes Nos. 4 and 7 have been sensed, thus placing two resistances 34 in parallel between the relay 35 and the voltage source. The two resistances 34 in parallel allow sufficient voltage to operate the relay 35. The solenoid 33 actuates a timing device 39, Fig. 4, of known construction described in Specification 396,805 which in turn actuates a lever 40 secured to a spindle 41 on which is mounted a deflector 42 disposed above a reject pocket.
